At this camp I had the unique experience of showing all these seasoned Westerners that it was possible to make a fire by the friction of two sticks. This has long been a specialty of mine; I use a thong and a bow as the simplest way. ↗

When I was little, I had this science book. There was a section on 'What would happen to the world if there was no friction?' Answer: 'Everything on earth would fly into space from the centrifugal force of revolution.' That was my mood. ↗

So, these political activities will create friction in and of themselves, and in this environment of friction there'll be additional violence. ↗

Change means movement. Movement means friction. Only in the frictionless vacuum of a nonexistent abstract world can movement or change occur without that abrasive friction of conflict. ↗

Iteration, like friction, is likely to generate heat instead of progress. ↗

I do not overlook the fact that the appearance of these new, free nations in the European political community not only celebrates the return of the prodigal son but also creates new sources of friction here and there. ↗

But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of the liberation of latent heat. ↗

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer. ↗
